Kalanchoe plant named ‘Fiveranda Orange’

ABSTRACT

A new cultivar of  Kalanchoe  plant named ‘Fiveranda Orange’ that is characterized by orange flowers, vigorous growth, strong branching, long flower life, short response time and a uniform crop.

Botanical classification: Kalanchoe guignardii×Kalanchoe blossfeldiana.

Variety denomination: ‘Fiveranda Orange’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Kalanchoe plant botanically known as Kalanchoe guignardii×Kalanchoe blossfeldiana and hereinafter referred to by the cultivar name ‘Fiveranda Orange’.

The new cultivar is the product of a breeding program conducted by the inventor in a cultivated area of De Lier, The Netherlands. The objective of the breeding program is to develop new Kalanchoe cultivars with interesting and unique flower colors and shapes.

‘Fiveranda Orange’ is a hybrid that originated from the induced hybridization of the female or seed parent Kalanchoe guignardii (not patented) and the male or pollen parent Kalanchoe blossfeldiana ‘Petero’ (U.S. Plant Pat. No. 12,155). The cultivar ‘Fiveranda Orange’ was selected by the inventor in 1999 as a single plant within the progeny of the stated cross in a controlled environment of De Lier, The Netherlands.

Asexual reproduction first occurred when terminal cuttings of the new cultivar ‘Fiveranda Orange’ were propagated in 2000 in De Lier, The Netherlands. Since that time, under careful observation, the unique characteristics of the new cultivar have been uniform, stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following represent the distinguishing characteristics of the new Kalanchoe cultivar ‘Fiveranda Orange’. These traits in combination distinguish ‘Fiveranda Orange’ as a new and distinct cultivar apart from other existing known varieties of Kalanchoe.

-   -   1. Kalanchoe ‘Fiveranda Orange’ exhibits vigorous growth.     -   2. Kalanchoe ‘Fiveranda Orange’ exhibits strong branching.     -   3. Kalanchoe ‘Fiveranda Orange’ exhibits a long flower life.     -   4. Kalanchoe ‘Fiveranda Orange’ exhibits a short response time.     -   5. Kalanchoe ‘Fiveranda Orange’ exhibits orange flowers.     -   6. Kalanchoe ‘Fiveranda Orange’ exhibits a uniform crop.

The new cultivar ‘Fiveranda Orange’ is distinguishable from the female parent Kalanchoe guignardii by the following characteristics:

-   -   1. ‘Fiveranda Orange’ exhibits orange flowers. The flowers of         the female parent Kalanchoe guignardii are red.     -   2. ‘Fiveranda Orange’ exhibits flowers that open more fully than         Kalanchoe guignardii.

The new cultivar ‘Fiveranda Orange’ is distinguishable from the male parent Kalanchoe ‘Petero’ by the following characteristics:

-   -   1. ‘Fiveranda Orange’ is larger than ‘Petero’.     -   2. ‘Fiveranda Orange’ exhibits orange flowers. The flowers of         ‘Petero’ are lighter orange.     -   3. ‘Fiveranda Orange’ exhibits stronger branching.

The closest comparison cultivar is Kalanchoe ‘Fiveranda Pink’ (U.S. Plant Pat. No. 16,189). The new cultivar ‘Fiveranda Orange’ is distinguishable from ‘Fiveranda Pink’ by the following characteristics:

-   -   1. ‘Fiveranda Orange’ exhibits orange flowers. The flowers of         ‘Fiveranda Pink’ are pink.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying photograph illustrates the distinguishing traits of Kalanchoe ‘Fiveranda Orange’. The plant in the photograph shows an overall view of a 18 week old plant. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the new Kalanchoe cultivar named ‘Fiveranda Orange’. Data was collected in De Lier, The Netherlands from 18 week glass greenhouse grown plants in 6 inch diameter containers. The time of year was Spring and the temperature was kept at 20° Centigrade during the day and night. The light level was natural outdoor light supplemented with artificial light below 10,000 lux. Photoperiodic treatments of 3 weeks of long days (more than 14 hours of light) followed by 8 weeks of short days (more than 14 hours of darkness) were used. No overhead watering was applied during the last 6 weeks. Color determinations are in accordance with The Royal Horticultural Society Colour Chart 2001 edition, except where general color terms of ordinary dictionary significance are used. The growing requirements are similar to the species. ‘Fiveranda Orange’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.
